DONE DEAL: Everton have announced the signing of Muhamed Besic [GETTY]

Besic, 21, represented Bosnia and Herzegovina in the World Cup and has been a target for Everton boss Roberto Martinez as he faces the challenges of strengthening the Toffees squad which he guided to a fifth place Premier League finish last season.

Speaking about the deal, boss Roberto Martinez said: "Muhamed is a young footballer who has developed massively in the last two seasons.

"He has been playing as a centre-half and as a defensive midfielder at an incredible level.

"What he did with Bosnia and Herzegovina in the World Cup, he showed that he is a really mature footballer, that he covers the ground really well, that he is very dynamic and technically very gifted.

"He is bringing us really good strength in an important part of the side."

Besic has become the second summer acquisition for Martinez, joining Gareth Barry at Goodison Park after the England international made his successful loan move to the Toffees permanent at the start of the month.
